Pulmonary Actinomycosis Imitating Lung Cancer on (18)F-FDG PET/CT: A Case Report and Literature Review.

Qiu L, Lan L, Feng Y, Huang Z, Chen Y - Korean J Radiol (2015)

Bottom Line: Here we report a case of 41-year-old man with a soft tissue density mass at right upper lung and palpable abscesses at right upper backside and right wrist. (18)F-fluorodeoxyglucose positron emission tomography/computed tomography demonstrated a 7.8 × 5.0 cm mass with soft-tissue density in the upper lobe of the right lung with high metabolic activity.Final diagnosis of pulmonary actinomycosis with multiple abscesses was made.The patient responded well to antibiotics treatment.

ABSTRACT
Here we report a case of 41-year-old man with a soft tissue density mass at right upper lung and palpable abscesses at right upper backside and right wrist. (18)F-fluorodeoxyglucose positron emission tomography/computed tomography demonstrated a 7.8 × 5.0 cm mass with soft-tissue density in the upper lobe of the right lung with high metabolic activity. The infiltrative mass extended to adjacent chest wall soft tissue. Final diagnosis of pulmonary actinomycosis with multiple abscesses was made. The patient responded well to antibiotics treatment.

Figure 1: 41-year-old man with pulmonary actinomycosis imitating lung cancer on 99mTc-MDP bone scintigraphy.A. Posterior. B. Uptake of radiotracer is increased at right third and fourth posterior ribs (small black arrows, A) and right multiple carpal bones (large black arrow, A).

Mentions: This report was approved by the Institutional Review Board of our institution. A 41-year-old man was admitted to our hospital with complaints of cough for 8 months. In addition, he had right thoracodorsal and shoulder discomfort as well as wrist swelling pain for 4 months. Physical examination found a palpable abscess at both right upper backside and right wrist. Blood routine examination and serum tumor marker analysis revealed no abnormality. A chest CT scan revealed a 7.8 × 5.0 cm lung mass in the right upper lobe with spiculated margins and irregular chest wall infiltration, suggesting peripheral lung carcinoma. Subsequently, a 99mTc-MDP whole bone scintigraphy was performed to determine whether there were bone metastasis. Bone scan (Fig. 1A, posterior) showed that the uptake of radiotracer was increased at the right third and fourth posterior ribs (small black arrows) as well as right multiple carpal bones (large black arrow). Regional chest and right wrist (Fig. 1B: B1, single photon emission computerized tomography [SPECT]; B2, CT; B3, SPECT/CT fusion) tomography imaging examinations found no osseous abnormality.
